Type
Pore Size Range
Typical Use
Effect on Liquid Clarity
Flow Speed
Qualitative (e.g., Grade 1)
8–11 μm
Routine lab filtration, removing larger sediments
Good for basic clarity (traps visible particles like sand or grounds)
Fast
Quantitative (e.g., Grade 5 or finer ash-free)
2.5–3.5 μm
Analytical work, gravimetric analysis
Best for high clarity (traps very fine particles, ideal for purifying solutions or beverages like wine)
Medium to slow
Glass Microfiber
0.7–2.7 μm
High-temperature or chemical-resistant filtration
Excellent for ultra-clear results in specialised cases (e.g., air pollution analysis), but less common for liquids
Fast (but requires flat use, not folding)
Specialty (e.g., Wine Filtration)
7–10 μm
Food/beverage clarification
High clarity for consumables, retaining fine sediments while preserving taste
Medium
